BESTFIT Mainspring WA14 for AS 1361, Wittnauer 11ARK, Benrus DA Automatics - Alloy

BESTFIT Mainspring with attached bridle WA14 for Wittnauer caliber 11ARK, Benrus caliber DA, and AS calibers 1361, 1336 automatics with bridle, plus perhaps similar ébauche watches, white alloy, new in envelope. See images for precise mainspring specifications. I likely have several of these so the one you get may differ slightly from the images. I specialize is hard to find watch parts so I usually have whatever you might need and all watch parts are unconditionally guaranteed. Images do a pretty good job of representing the item.
